The invention provides a Y-contained high-abundance rare earth permanent magnet. The magnet comprises RealphaYbetaBgammaMxNyFe100-alpha-beta-gamma-x-y, wherein Re includes at least Nd and Ce; M is selected from Co and / or Cu; N is one or more elements selected from a group consisting of Nb, Ti, Zn, Ga, Al, Zr, Sn, Sb, Ta and W; alpha, beta, gamma, x and y are weight percentages of the respective elements, 23 <=alpha <=35, 0 < beta<=10, 0.95 <=gamma <=1.2, 0 <=x <=2, and 0 <=y <=2; the main phase grain of the Y-contained high-abundance rare earth permanent magnet is of a core-shell structure, element Y is more distributed at the core, Ce and Nd are more distributed in a shell layer, so that the loss of coercive force caused by the addition of Ce in Nd-Fe-B is compensated, and meanwhile temperature stability of use is improved.
